3. Insert the screws through the holes on the mounting bracket and
into the screw holes on the MMAC-M3FNB.
4. Tighten the screws until the mounting bracket is securely attached
to the unit.
5. Repeat steps 2-4 for the second rack mount bracket. Be sure to use
the same set of holes on the second rack mount bracket (front for
flush mount, rear for recessed mount) that you used on the first
bracket; also, be sure to use the longer (3/8”) screws provided in the
accessory pack when mounting the left bracket.
6. Slide the unit into the rack.
7. Align the slots on each mounting bracket with the desired holes on
the equipment rack. Be sure to leave enough space below the unit
for installation of the cable tie tray, if desired.
8. Insert bolts (item 5) through the slots in each of the mounting
brackets and into the threaded holes in the equipment rack (item
6). Secure bolts with locking washers.
9. Tighten the nuts and bolts until the unit is secured to the rack.
3.2.2 Rack Mounting the Cable Tie Tray
A cable tie tray is provided with the MMAC-M3FNB to support and
organize cables connected to the unit. The tray is designed to be
installed directly under the MMAC-M3FNB in the equipment rack. To
mount the cable tray in a standard 19" equipment rack:
On the right-hand side of the chassis, use the same
screws you removed in step 1, above; on the left-hand
side, use the longer (3/8”) screws provided in the
accessory pack. It is very important that you use the
longer screws on the left side! The shorter screws
will provide inadequate support, and the bracket will
not be securely mounted to the chassis.
